Series 5500 - Straight Shank

Guhring SpyroTec - The Innovative, Twisted HSCO Countersink

Series 5500 - With Ground Shanks for use in Collet Chucks etc

* Universal Application in nearly any Material
* Round, Precise and Chatter-Free Countersinking is guaranteed
* Reduction of Feed Force by 60%
* Reduction of Radial Force by 50%

The axial and radial forces that occur during countersinking operations are greatly reduced due to the newly developed geometry of the SpyroTec cutting edges. Due to convex different radii of the cutting edges with variable helical pitch provide a stable and low-vibration countersinking process. The specially designed TiAlN coating ensures a higher wear resistance and high-temperature hardness which guarantee longer tool life of nearly all materials and applications.
